Answer:
wavelength: the distance between successive crests of a wave
frequency: the rate per second of a vibration constituting a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light)
electromagnetic energy is used for wifi, cell phones, microwave ovens etc.
the electromagnetic spectrum includes radio waves, microwaves, infrared radiation, visisble light, ultraviolet, xrays and gamma rays
the only part we can see is visible light
visible light can be characterised by the colours of the rainbow
the longest wavelength is red and the shortest is violet
when combined, the colour is perceived as white or beige
Answer:
Just as wavelength and frequency are related to light, they are also related to energy. The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy.
Explanation:
WAVELENGTH=
PHYSICS
the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
"a range of wavelengths"
2.
a person's ideas and way of thinking, especially as it affects their ability to communicate with others.
"when we met we hit it off immediately—we're on the same wavelength"
FREQUENCY=
Frequency, in physics, the number of waves that pass a fixed point in unit time; also, the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.
ENERGY=
energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another.

What are the mechanism that use to resist the antimicrobial agents?There has been several mechanisms, like resistance to antimicrobial agents, encapsulation or secretation of proteins that affects and might destroy the phagocyte along with some leukocytes in our body perform phagocytosis as a defense mechanism against the pathogenic bacterium.
These phagocytes contain lysosomes, intracellular granules that possess bactericidal substances. When the phagocyte ingests the pathogen, a phagosome is formed, which merges with the lysosome, forming the phagolysosome, which is where toxic substances and enzymes kill the ingested microorganism.
There are several mechanisms by which a microorganism can survive this process as resistance to antimicrobial agents. Some bacteria use phenolic glycolipids from their cell wall, to eliminate toxic oxygen compounds.

A. Fossil fuels provide cheaper energy.
B. We have very efficient means of using fossil fuels currently.
C. We already have infrastructure in place to make use of fossil fuels.
D. Fossil fuels provide cleaner energy.
Answers
Explanation:
A ) Fossil fuels provide cheaper energy
MARK AS BRAINLIST IF IT IS USEFUL .
Fossil fuels are a non-renewable resource that takes years to form. They are the source of large energy production and provide cost-efficient cheaper energy. Thus, option A is correct.
What are fossil fuels?Fossil fuels are the dead remains that got converted into sediments and over millions of years produced the fuels used to drive energy. They are produced from deposition of the organic matter and are widely used resources for energy.
They are present in the crust of the earth and are a cheaper form of energy than wind and geothermal energy. They are found in the form of coal, petrol, diesel, and other natural gases. They are produced from decaying organic matter.
These fuels are less costly than the alternative form of energy, however, are the reason for increased temperature and climate change. They have added to the greenhouse gases and are major pollutants.
Therefore, option A. fossil fuels are cheaper.

What is the frequency of a wave that has a wavelength of .20 m and a speed of 22 m/s
Answers
Answer:
110 Hz
Explanation:
Find the frequency of the wave using the formula, frequency = speed / wavelength.
Plug in the speed and wavelength, and solve:
frequency = speed / wavelength
frequency = 22 / 0.2
frequency = 110
So, the frequency of the wave is 110 Hz
